SHEET-DELIVERY APPARATUS.

SPECIFICATION forming part of Letters Patent No. 678,044, dated July 9, 1901. Application filed May 19,1897. Serial No. 637,173. (No model.)

paratus, of which the followingis aspecilication.

The present invention relates to street-delivery apparatus for that class of `machines commonly known as bed-and-cylinder printing-presses, and has for its object the delivery of the printed sheets with the freshlyprinted sides uppermost, the simplification of the construction and operation of the mechanism, and other objects, as will hereinafter appear. v I

To these ends the invention includes com binations of devices hereinafter described,

and more fully pointed out in the claims con cluding this specification.

The preferred form of the present inven-l tion is illustrated in the accompanying drawings, forming part thereof, in Which- Figure l is a side elevation of part of a inachine in which the invention is embodied. Fig. 2 is a partial plan view of the machine shown in Fig. l. Fig. 3 is a view, partly in section looking toward the impression-cyl-- inder, of the sheet-support shown in Figfl and operating mechanism therefor. Figult is a view from the end of the delivery-board, showing adjustable stops and guidesfor the sheets. Fig. 5 is a plan view showing the support and other parts in positions different fromthose shown in Fig. 2 and parts being omittedfor the sake of clearness. Fig. 6 is a detail View, partly in section.

The impression-cylinder and the type-bed may be of any usual or suitable construction and may be operated in any of the usual Ways. Hence no mechanism for operating them is shown nor will such mechanism be described. The sheets may be delivered directly or indirectly fromv the cylinder upon the extensible collapsible'sheet-support 6. In the case shown the sheets are delivered indirectly byY ineansof the endless t-apes B, which'run upon suitable rollers or pulleys 25, which are driven from the impression-cylinder o r other part of the machine. A set of guide-fingers F maybe employed in conjunction with the tapes Bin the feeding of the sheets forward upon thesheet-support C. Thesupport `C may be in the form of a fablric or a set of discontinuous tapes fast at one endtothe bar K and at the other end to the rollerD. ln'that form of the invention illusvtrated in the drawings the roller Dis hollow and is loosely mounted upon a shaft M,which is-journaled in boxes p on the travelers n,

-running on the racks O, through the medium the racks O, above named, and at one end 1 with a pinion P, which is in mesh with. aY

movable rack R. The rack R is suitably guided on the frame of the machine and is wide enough to mesh with the pinion S, fast on the short shaft r, which is journaled in the frame. The pinion P is less lthan the pinion N in diameter or size. The movable rack R exerts its power on the pinion P at a point between its axis of motion and the point where pinion N at that side meshes Withthe rack O, thus causing the roller D to bemoved out and in faster than the rack R. The shaft r is provided with a pinion Y, by means of which it is operated, as hereinafter set forth. The racks O extend from the point where the support C receives the ,sheets to near the roller W at the end of the machine. This roller W is loosely mounted on the fixed stud a and is moved in the direction ofthe arrow by means of the spring X, which is coiled about the stud a loosely and has its ends fast to the roller W and to the framework of the machine. A ligament, as a tape U, is fast at one end tok the roller W and at the other end to the roller D above named. The ligament U and the support C are fast to the roller D in such wise that one is woundupon the roller D as the other is wound olf the same. In order to prevent the sheets from rising from the support C, a set -of fixed guide-fngersG are employed,these `lingers being borne by the bar b, which extends across the framework of the machine,

being supported from the bar K by the arms.

d. A set of guide-fingers F are shown for use in conjunction with the tapes B for alike purpose. These guides F may be raised and IDG the pinion Y, the bar e, connecting the rack T and the bell-lever Z, and the bar h, connecting the lever Z and the crank-arm t'. The crank t'. is rotated in proper time by gearing connecting it with the driving mechanism of the the press. (None of this is shown.) The rod e by preference is adjustably connected with i the bell-lever Z, as by the arcshaped slot 2,

so that the distance between the center of motion of the lever and the point of connection of the rod may be varied. The pin 3, which connects the rod e and the slotted lever, maybe moved and held in position by means of the rod 4, which is screw-threaded exteriorly, and the hollow nut 5 and the hollow shaft G, which carries the nut. The shaft (i is suitably swiveled in the bell-lever Z to swing in a vertical plane and is provided with a hand-wheel 7, whereby it is operated. The radius of the slot 2 is equal to the length of the rod or link e.

The delivery-board E is provided with adjustable stops H for the heads of the sheets. The stops ll are pivoted to a board 9 at the points 8, the said board being provided with T-heads 10, which engage under the lips or flanges 11 to the board E and overhang,r the edges of the grooves 12 therein. These grooves 12 (of which but one is shown) extend toward and from the impression-cylinder on the top of the hoard E. A spring 13, coiled about 'the axis 8 of the stop H, bears against the back of the stop H and on top of the board E and retains the stop in an upright position. The board E is also provided with adjustable side guides or stops J for the sides of the sheets, the said guides being carried by the arms 14. (The guides J above or at one side of the machine are omitted from the drawings.) The arms 14 are provided with collars 15, which are adjustably held on the rods 16, as by set-screws, the rods 16 being adjustably held by the perforated plate 17. These plates 17 are adjustable transversely of the machine by means of the slots 19 therein and the headed tap-bolt 18 or by a nut instead of the head on said bolt.

The means shown in the drawings for adjusting the position of the pin or stud 3 along the slot 2 comprises an arm 31, projecting laterally from the lever Z, a bearing comprising two plates or blocks 32 33, secured to each other and having horizontal journals which engage with suitable bearings in the arm 31, a hollow shaft 6, having a iiange held between the plates 32 33, whereby the shaft swivels in the bearing formed by said plates and the said plates pivot or hinge upon the arm 31, and a hand-wheel 7 on the shaft G, with a nut 5, to which the shaft 6 is fixed to turn the nut, and a screw-threaded rod 4,

machine is working or in motion by turning the handle 7 and shaft U, whereby the nut 5 will be turned to draw rod 4f into orto force it outward of the shaft and so to move the pin 3 toward or from the axis of motion of the le- Ver Z and so to vary the throw of the rack T and the delivery.

The operation of the devices above described is as follows: The sheets are run out from theimpression-cylinder onto the endless tapes B, which carry the sheets forward onto the discontinuous support C, which at this time is beginning to unroll from the roller D as the latter' is carried outward or away from the impression cylinder by the described mechanism. The roller D is moved at a rate of speed sufficient to keep the sheet from overrunning the roller. As the support C is unwoundfrom the roller D the ligament U is wound on the roller. It is understood, of course, that the ligament is at one side (edge) of the support out of the way of the sheets and does not overlap the support, or rather that the tape U shall not be in the path of the sheets, for it may overlap the support. The sheets are fed onto the support bythe tapes B and the rollers 2l, the latter being borne bythe arms F, which are supported by the shaft 28 near the impression-cylinder. The shaft 28 may be and preferably is journaled in the frame, so that the guides F and rollers 21 (in case the guides F are fast to the shaft) may be lifted or swung up out of the way, or the guides F may be pivoted on the shaft (fixed in the framework) and be so lifted up or swung. After the roller D begins to return from its extreme position the sheets drop oit head first onto the board E, being guided in so doing by the stops H and guides J and are thus piled evenly. The ligament U turns the roller D as the latter is drawn backward by the shaft M,thus winding up the support C while unwinding the tape U. The shaft M is moved bodily to and fro by means of the racks O R, the pinions S Y, rack T, rod e, bell-lever Z, rod H, and crank t', the last being driven in unison with the bed 23- that is, the crank makes one complete revolution while the bed is making one complete excursion to and fro. The spring X takes up any slack in the support C, as will be understood.

The devices are shown in the positions they occupy when the sheets are of the maximum size the machine will print. When narrower sheets are printed, the stops J are adjusted toward the center of the board E. When shorter sheets are delivered, the stops H are adjusted toward the impression-cylinder, as are the guides J, and the pin 3 is moved toward the center of motion of the bell-lever Z by the described means.

Another feature of the invention is that the guides 26, which are borne by the shaft 27, are so arranged as not to interfere with the adjustment of the pulleys transversely of the machine, as by set-screws 34, securing them to their shafts. The fingers F are adjustable transversely of the machine in order that the rollers 2l may always coperate with the rollers 25 and feed the sheets forward. The rollers 2l are borne by crank-arms which are pivoted to the fingers F and bear bytheir weight on rollers 25. l

The guides G are movable or adjustable end-V wise in the holders 30, whichthemselves are adjustable longitudinally and circumferenthe combination of the delivery-board, a holtially of the shaft b.

It is obvious that the sheets may be run directly upon the support C, which in such case would be placed adjacent the im pression-cylinder, thus dispensing with the tapes B and accessories.

It is immaterial what means be employed for reciprocating the roller D, as the described arrangement of the support and the ligament U sufce to rotate it.

It is obvious that many changes in the ar-` rangement ot' parts, substitutions of equivalents, &c., may be made without departing from the spirit of the invention. Accordingly Ido not limit myself tothe form thereof shown in the drawings and hereinbefore described.
